Just Dance sells 4.3 million globally

At a media event in San Franciso, French publisher Ubisoft announced that its surprise hit Just Dance has shifted more than 4 million copies worldwide since its launch last year.

In light of the game's astronomical success, Ubisoft's marketing senior vice president Tony Key anticipates that the genre will become a big money-maker for the publisher.

"This dance category is going to explode. We dont know how big it can be I think its much bigger than what anybody realizes at the moment," Gamasutra quotes Key as saying. "I think theres a real market for that kind of entertainment at home."

Ubisoft will continue to produce titles in the category this winter, with Just Dance 2 and Michael Jackson: The Experience both set to hit shelves before the end of the year. Meanwhile, Rock Band developers Harmonix are producing their own rhythm game, Dance Central, for Microsoft's Kinect.
